Abstract

A food slicer includes a frame for supporting a landing and a runway, which is movable relative to the landing. A cutting blade is secured on an upstream end of the landing. A separate cutting knife is moveably connected to the frame. An adjustment mechanism is connected to the frame to adjust an offset between the cutting blade and the runway. The adjustment mechanism includes first and second guide tracks provided on respective first and second movable cam plates, and a gear mechanism for moving the first and second cam plates along a length direction of the food slicer.

First claim

What is claimed is:

1. A mandoline-type food slicer for slicing food advanced in a cutting direction, the food slicer comprising:
a frame for supporting a landing and a runway, which is movable relative to the landing;
a cutting blade secured on an upstream end of the landing, a downstream end of the runway being spaced from an edge of the cutting blade to define an opening for the passage of sliced food;
a separate cutting knife moveably connected to the frame; and
an adjustment mechanism connected to the frame and configured to adjust an offset between the cutting blade and the runway, the adjustment mechanism including:
spaced apart first and second guide tracks provided on respective first and second cam plates, and
a gear mechanism for moving the first and second cam plates along a length direction of the food slicer,
wherein the adjustment mechanism simultaneously engages the runway and the cutting knife, the first guide tracks cooperating with the downstream end of the runway and the second guide tracks cooperating with the cutting knife,
wherein the first and second guide tracks are configured such that a first movement of the adjustment mechanism from a locked position of the food slicer to a cutting position lowers the downstream end of the runway relative to the cutting blade to adjust a cutting thickness and a second movement of the adjustment mechanism from the cutting position raises the cutting knife to a working position.

2. The food slicer of claim 1 , wherein the gear mechanism includes a first pinion gear meshingly engaged to a first rack connected to the first cam plate.

3. The food slicer of claim 2 , wherein the gear mechanism includes a second pinion gear meshingly engaged to a second rack connected to the second cam plate.

4. The food slicer of claim 3 , wherein the first and second racks are integral with the respective first and second cam plates.

5. The food slicer of claim 3 , further including a shaft interconnecting the first and second pinions gears and a knob connected to an end portion of the shaft extending outwardly from the frame.

6. The food slicer of claim 1 , wherein the gear mechanism is configured such that the first movement of the adjustment mechanism simultaneously lowers the upstream end of the runway.

7. The food slicer of claim 6 , wherein the gear mechanism includes a first cam engaging the upstream end of the runway, wherein rotation of the first cam lowers the upstream end of the runway.

8. The food slicer of claim 7 , wherein the gear mechanism further includes a second cam engaging the upstream end of the runway.

9. The food slicer of claim 8 , wherein the first and second cams include respective first and second guide surfaces and the upstream end of the runway includes one of laterally spaced projections and a pin engaging the first and second guide surfaces.

10. The food slicer of claim 9 , wherein the frame includes elongated openings cooperating with the projections on the upstream end of the runway.

11. The food slicer of claim 1 , wherein the first guide track of the first cam plate includes an upstream section, a central section and a downstream section, and defines a first upward sloping surface from the central section toward the upstream section and a second upward sloping surface from the central section toward the downstream section,
wherein the first movement of the adjustment mechanism moves the downstream end of the runway along the first sloping surface from the downstream section toward the central section and the second movement of the adjustment mechanism moves the downstream end of the runway along the second sloping surface from the central section toward the upstream section, and
wherein the runway is at its lowermost position in the central section.

12. The food slicer of claim 11 , wherein the second guide track of the first cam plate includes a downstream section and an upstream section which is sloped relative to the downstream section, wherein the second movement of the adjustment mechanism moves the cutting knife along the upstream section to the working position.

13. The food slicer of claim 12 , wherein the upstream section of the second guide track includes a first sloping surface slope upward toward the first guide track and a second sloping surface sloped downwardly away from the first guide track,
wherein the cutting knife is a first cutting knife and further including a second cutting knife cooperating with the second guide tracks of the first and second cam plates, and when the second cutting knife is in the working position the first cutting knife is positioned along the second sloping surface.

14. The food slicer of claim 12 , wherein the orientation of the first and second guide tracks provided on the second cam plate is substantially a mirror image of the orientation of the first and second tracks provided on the first cam plate.

15. A mandoline-type food slicer for slicing food advanced in a cutting direction, the food slicer comprising:
a frame for supporting a landing and a runway, which is movable relative to the landing;
a cutting blade secured on an upstream end of the landing, a downstream end of the runway being spaced from an edge of the cutting blade to define an opening for the passage of sliced food;
a separate cutting knife moveably connected to the frame; and
an adjustment mechanism connected to the frame and configured to adjust an offset between the cutting blade and the runway, the adjustment mechanism including:
spaced apart first and second guide tracks provided on respective first and second cam plates, the first guide tracks cooperating with the downstream end of the runway and the second guide tracks cooperating with the cutting knife, and
a gear mechanism for moving the first and second cam plates along a length direction of the food slicer, the gear mechanism including:
a first pinion gear meshingly engaged to a first rack connected to the first cam plate,
a second pinion gear meshingly engaged to a second rack connected to the second cam plate,
a shaft interconnecting the first and second pinions gears,
first cam associated with the first pinion gear, and
a second cam associated with the second pinion gear.

16. The food slicer of claim 15 , wherein the adjustment mechanism simultaneously engages the runway and the cutting knife, and
wherein the first and second guide tracks are configured such that a first movement of the adjustment mechanism from a locked position of the food slicer to a cutting position lowers the downstream end of the runway relative to the cutting blade to adjust a cutting thickness and a second movement of the adjustment mechanism from the cutting position raises the cutting knife to a working position.

17. The food slicer of claim 16 , wherein the gear mechanism is configured such that the first movement of the adjustment mechanism simultaneously lowers the upstream end of the runway.

18. The food slicer of claim 17 , wherein the first and second cams engage the upstream end of the runway, wherein rotation of the first and second cams lowers the upstream end of the runway.

19. The food slicer of claim 17 , wherein the first and second racks are integral with the respective first and second cam plates, and the first and second cams are integral with the respective first and second pinion gears.

20. The food slicer of claim 16 , wherein the first guide track of the first cam plate includes an upstream section, a central section and a downstream section, a
